This paper proposes an evaluation framework to provide a comprehensive overview of the current state of the copyright protection measures for GANs, evaluate their performance across a diverse range of GAN architectures, and identify the factors that affect their performance and future research directions.
- Farina Riaz, Shahab Abdulla, Hajime Suzuki , Srinjoy Ganguly, Ravinesh C. Deo, and Susan Hopkins, “Accurate image multi-class classification neural network model with quantum entanglement approach,” Sensors (Impact Factor 3.85), March 2023. 11 pages. https://doi.org/10.3390/s23052753. This is the first paper published from the new Quantum ML for Cyber project. In this paper, we propose a novel neural network with quantum entanglement method to enhance the accuracy of image classification. We show the improvements in image classification accuracy over 10 class hand written digits and photos but not over 43 class real-life traffic signs. Exact causes of the improvement and degradation are currently open questions and requiring further investigation.
- Chehara Pathmabandu, John Grundy, Mohan Baruwal Chhetri, Zubair Baig, Privacy for IoT: Informed consent management in Smart Buildings, Future Generation Computer Systems, Volume 145, 2023, Pages 367-383, The impact factor of this venue is quite high – It’s 7.18. Link: https://doi.org/10.1016/j.future.2023.03.045. (https://www.sciencedirect.com/science/article/pii/S0167739X23001322). The paper proposes a novel Informed Consent Management Engine (ICME) to handle the tension between personal data disclosure and convenience in shared smart spaces, accompanied by a rigorous evaluation. The main objective of our study is to design an appropriate mechanism for Smart Building consent management comprising a generalised reference architecture and to instantiate a comprehensive framework for user consent management in Smart Buildings to mitigate the privacy paradox. We also highlight in our work; the observation of perceived usefulness, benefits, challenges of the solution, and impact on the environment/SB stakeholders.

Asymmetric Numeral System (ANS) is a compression algorithm invented by Jarek Duda in 2009, which has taken the IT industry by storm. The paper investigates compression rate of ANS. It turns out that the main component of ANS is its symbol spread, which can be chosen arbitrarily. However, for each symbol spread ANS has a slightly different compression rate. The paper gives an algorithm that maximizes the compression rate.

Towards Proactive Risk-aware Cloud Cost Optimisation Leveraging Transient Resources. Accepted to IEEE Transactions of Services Computing (Impact Factor: 11.019). The paper proposes an approach for risk-aware cloud cost optimisation that is inspired by the concept of portfolio diversification. Contract diversification mitigates the resource revocation risk by procuring the required compute capacity as a mixed portfolio of transient and non-transient resources. Resource diversification further diversifies the risk by using multiple transient resource types.

A novel graph-theoretical clustering approach to find a reduced set with extreme solutions of Pareto optimal solutions for multi-objective optimization problems. Accepted to Journal of Global Optimization, 2023 (journal ranking: A). This paper proposes a novel graph-theoretical clustering method to identify representative solutions of a large number of Pareto optimal solutions obtained from multi-objective optimisation problems. The identified representative solutions help decision makers to select suitable solutions among the large set of Pareto optimal solutions, which are all optimal with some trade-offs. The proposed method outperforms the traditional clustering approaches in Pareto pruning like K-means clustering.

- Ruoxi Sun, Minhui Xue, Gareth Tyson, Tian Dong, Shaofeng Li, Shuo Wang, Haojin Zhu, Seyit Camtepe, and Surya Nepal, Mate! Are You Really Aware? An Explainability-Guided Testing Framework for Robustness of Malware Detectors, Accepted, The ACM Joint European Software Engineering Conference and Symposium on the Foundations of Software Engineering (ESEC/FSE, CORE A*), In this work, we propose an explainability-guided and model-agnostic testing framework for robustness of malware detectors when confronted with adversarial attacks. According to our findings, we suggest that machine learning-based antivirus products should consider adopt the proposed approach to enhance their robustness. We believe that exploring this aspect further could prompt a new approach to defending against malware evasion attacks. Our findings shed light on the limitations of current malware detectors, as well as how they can be improved. Future collaboration with security experts from the industry is feasible.

- Ruoxi Sun, Minhui Xue, Gareth Tyson, Shuo Wang, Seyit Camtepe and Surya Nepal, Not Seen, Not Heard in the Digital World! Measuring Privacy Practices in Children’s Apps, Accepted, The Web Conference (WWW, CORE A*), In this paper, we explore the potential privacy issues and threats that exist in children’s mobile apps. Our findings suggest that, despite significant attention to children’s privacy, a large gap between regulatory provisions, app store policies, and actual development practices exist. After we disclosed our findings to the Google privacy team, the Play store updated the FAMILY category requirement and the Families policy. Our research sheds light for government policymakers, app stores, and developers. Collaboration with the Google privacy team could expand this study further. EP2023-0479
